Linux commands to copy one file to many files
提问by user121196
Is there a one-line command/script to copy one file to many files on Linux?
在 Linux 上是否有一行命令/脚本可以将一个文件复制到多个文件？
cp file1 file2 file3
copies the first two files into the third. Is there a way to copy the first file into the rest?
将前两个文件复制到第三个文件中。有没有办法将第一个文件复制到其余文件中？

Does
做
cp file1 file2 ; cp file1 file3
count as a "one-line command/script"? How about
算作“单行命令/脚本”？怎么样
for file in file2 file3 ; do cp file1 "$file" ; done
?
?
Or, for a slightly looser sense of "copy":
或者，对于“复制”的稍微宽松的感觉：
tee <file1 file2 file3 >/dev/null

The simplest/quickest solution I can think of is a for loop:
我能想到的最简单/最快的解决方案是 for 循环：
for target in file2 file3 do; cp file1 "$target"; done
A dirty hack would be the following (I strongly advise against it, and only works in bash anyway):
一个肮脏的黑客将如下（我强烈建议不要这样做，无论如何只能在 bash 中工作）：
eval 'cp file1 '{file2,file3}';'

You can use standard scripting commands for that instead:
您可以改为使用标准脚本命令：
Bash:
重击：
for i in file2 file3 ; do cp file1 $i ; done
回答by Matt
for FILE in "file2" "file3"; do cp file1 $FILE; done

You can use shift:
您可以使用shift：
file=
shift
for dest in "$@" ; do
cp -r $file $dest
done

Use something like the following. It works on zsh.
使用类似以下内容。它适用于 zsh。
cat file > firstCopy > secondCopy > thirdCopy
cat 文件 > firstCopy > secondCopy >thirdCopy
or
或者
cat file > {1..100} - for filenames with numbers.
cat 文件 > {1..100} - 用于带数字的文件名。
It's good for small files.
它适用于小文件。
You should use the cp script mentioned earlier for larger files.
对于较大的文件，您应该使用前面提到的 cp 脚本。

just for fun, if you need a big list of files:
tee <sourcefile.jpg targetfiles{01-50}.jpg >/dev/null- Kelvin Feb 12 at 19:52
只是为了好玩，如果您需要大量文件：
tee <sourcefile.jpg targetfiles{01-50}.jpg >/dev/null-开尔文 2 月 12 日 19:52
But there's a little typo. Should be:
但是有一点错别字。应该：
tee <sourcefile.jpg targetfiles{01..50}.jpg >/dev/null
tee <sourcefile.jpg targetfiles{01..50}.jpg >/dev/null
And as mentioned above, that doesn't copy permissions.
如上所述，这不会复制权限。

You can improve/simplify the forapproach (answered by @ruakh) of copying by using rangesfrom bash brace expansion:
可以提高/简化for通过使用复制的方法（由@ruakh回答）范围从bash中括号扩展：
for f in file{1..10}; do cp file $f; done
This copies fileinto file1, file2, ..., file10.
这复制file到file1, file2, ..., file10.
